首先建议你安装一个扩展库安装工具，推荐easy_install工具，你可以在网上下载，也可以先去下载一个 ez_setup.py ，这个程序下载后用python.exe运行一下，会自动根据你的版本帮你下载和安装一个easy_install，目前只支持到python2.6，看来python3目前还是没有太多的公司在使用啊。。。
后面就可以用这个easy_install工具进行第三方库的下载了，比如我要下载soaplib这个库，可以执行easy_install soaplib，它会自己去相关网站查找这个库，以及这个库的依赖，如果你手工安装，那依赖会把你搞疯掉的
关于哪个库更适用做webservice
现在网上查到最多的是ZSI或者叫soappy，实际上05年之后就没有更新了，而且只支持到2.5，放弃
soaplib，这个目前2.0，还是不错的，不过手册不是太好读，只有server端的用法，client我没找到suds，这个我在用，用起来比较简单，示例代码如下：
[python] view plain copy
The library is now ready to use. We start by importing the suds library, creating a client based on a SOAP url, and asking the library to print the SOAP web service methods that are available to us.
import suds
url = "http://www.ecubicle.net/iptocountry.asmx?wsdl"
client = suds.client.Client(url)
print client
From the output of the last print command, we learn that there is a method called FindCountryAsString that takes one argument: the IP address.
print client.service.FindCountryAsString("194.145.200.104")
And it shows (edited for readability):
<?xml version="1.0"?>
<IPAddressService>
<country>Netherlands</country>
</IPAddressService>
Normally you want to have the contents of the SOAP body. This is what suds provides in a very elegant way. However, you’re a bit stuck when you want to get something from the SOAP header. The author of suds realised this and made a backdoor to get the information anyway. We start by showing what the function last_received contains:
print client.last_received()
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope>
<soap:Header>
<ResponseHeader xmlns="">
<resultCode>1000</resultCode>
<resultDescription>Success</resultDescription>
</ResponseHeader>
</soap:Header>
<soap:Body>
...
</soap:Body>
</soap:Envelope>
We can get portions of this data by doing some XML handling. Let’s say we want to print the resultCode:
print client.last_received().getChild("soap:Envelope").getChild("soap:Header")
.getChild("ResponseHeader").getChild("resultCode").getText()
